The Sony PlayStation Phone plot thickens once again as yet more supposed prototype pictures and details of the rumoured device hit the web.

Engadget, who first leaked pictures of the smartphone/PSP mash-up, now have further snaps which appear to confirm that the device will be known under the codename Zeuz as the site first suggested, and have a 8GB microSD slot and 512MB of internal storage.

The latest PlayStation Phone snaps also show the device running on Android 2.2, but it's believed that there are numerous devices running different versions of Google's mobile OS, which includes one packing Android 3.0.

Despite new evidence of the PlayStation Phone's existence seemingly building up by the day, Sony continues to adopt the stance of not commenting on rumour or speculation.
